Surface Tension and Water Temperature
Broad Question
Does the surface tension change depending on the temperature of the water?Specific Question
Will 40, 65 or 80 degree Fahrenheit have more surface tension?Variables
Independent Variable: Water temperature
Dependent Variable: Surface tension, number of drops of water
Variables That Need To Be Controlled: Penny, water, thermometer
Hypothesis
I hypothesize that the 80 degree water will have more surface tension, followed by 65 degree then 40 degree.Graph of Hypothesis
Experimental Design
I will conduct this experiment either at home or at my aunts house. I will get all of my materials. Heat and cool the water to the temperatures that are needed. I will set out a few pennies. Then I will see how many drops of each temperature of water I can get on each penny. I will record the data directly on to my laptop.Materials List
